FTS Report on DOY 172

I.  The following are clock offsets, in microseconds between the clocks
at each DSN complex and each complex relative to UTC(NIST).  The offset
is a mean of readings using several GPS space vehicles in common view.

II.  Frequency Offsets from linear least-squares fits on time-offsets
over the period (53897 to 53906):

III.  Comments:
* Values derived from linear least squares extrapolation or interpolation
! There were not enough common view SV between SPC 10 and SPC 60 for DOY 162 (MJD 53897) and DOY 171 (MJD 53906).
% Power supply to the SPC 60 CRG failed and had to be replaced on DOY 166 (MJD 53901).Timing was re-synched to GPS receiver.
